[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a golf putter.

[0002]

[Prior art]

In a conventional putter, for example, a head is fixed to one end of a shaft, and a grip is attached to the other end of the shaft. Normally, the weight of the head is about 330g, the weight of the grip is about 70g, the weight ratio of the head and the grip is about 330g: 70g = 5: 1, the area of the sole part of the head is about 24cm ² , and the end part of the grip is about The area is about 6 cm ² , and the area ratio of the sole part to the end part is about 24 cm ² : 6 cm ² = 4: 1, and the head is large and the grip is thin. Further, there are various types of heads, such as those in which a cavity is formed in the back portion, and those in which the entire head is a semi-cylindrical shape. When using this kind of putter, for example when putting on the green, grasp the grip with your hand, read the flight line to the cup by addressing it, and then square the face surface of the head on the flight line ( Stroke (shake) the head in the direction of the flight ball line. Then, the ball is hit on the face surface of the head and rolls toward the cup.

[0003]

[Problems to be solved by the device]

 However, in the conventional putter, since the grip is relatively thin to hold it by the hand and the head is formed to be large for hitting the ball, the following problems ( There were a) and (b), and it was difficult to solve them. (A) At the time of putting, since the head is considerably larger than the thickness of the grip, the ball easily comes off the sweet spot (core) of the head. In other words, the larger the head, the more unclear the sweet spot. When the ball comes out of the sweet spot, the ball rolls poorly and shorts out of reach of the cup, or if the green is tilted and has a slice line or hook line, the ball often bends and comes out of the cup. . (B) In order to solve the above problem (a), it is conceivable to make the head smaller. However, when the head is made smaller, the grip is thin, and the head shakes and the head shakes, which makes it difficult to get a long putt line because the direction and sense of distance do not match. Therefore, it is still difficult to obtain a putter having excellent directionality and sense of distance.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, a first invention is a putter in which a head is fixed to one end of a shaft and a grip is attached to the other end of the shaft, and a weight ratio between the head and the grip is 3%. : 1 to 1: 1 and the area ratio between the sole portion of the head and the end portion of the grip is set to 3: 1 to 1: 1. In the second invention, in the putter of the first invention, a cavity is formed between the toe side and the heel side of the back portion of the head. According to a third aspect, in the putter according to the first or second aspect, a guideline is formed on a top portion of the head on a sweet spot of the head and in a direction perpendicular to a face surface of the head. ing. According to the fourth invention, in the putter of the first, second or third invention, a guide mark is formed at the end portion of the grip in a direction orthogonal to the face surface of the head. According to the fifth invention, in the putter of the first, second, third or fourth invention, another guideline is formed in parallel with the central axis of the shaft on the front surface of the outer periphery of the shaft.

[0005]

[Action]

 According to the first invention, since the putter is configured as described above, the head becomes smaller and the grip becomes thicker than the conventional one. The small head has the function of clarifying the sweet spot. In addition, the big size grip has the function of improving the gripping force, suppressing the shake of the hand and the accompanying shake of the head, and facilitating the long pad strike. This improves the directionality and distance feeling during putting. According to the second invention, the cavity formed in the head has the function of improving the moment of inertia by the weight distribution between the toe side and the heel side and further increasing the sweet spot. According to the third invention, the guide line formed on the top portion of the head serves as a guide when the face surface is aligned with the square in the flight line direction. According to the fourth invention, the guide mark formed on the end portion of the grip serves as a guide for correctly aligning the face surface with the square at a distance closer to the eyes. According to the fifth invention, the guide line formed on the outer peripheral front surface of the shaft has a function of making it easier when the face surface is aligned with the flying line in a square shape. Therefore, the above problem can be solved.

【Example】

1 is a side view of a putter showing an embodiment of the present invention, FIG. 2 is a front view of FIG. 1, FIG. 3 is an enlarged perspective view of the head in FIG. 1 seen from above, and FIG. 4 is a grip in FIG. It is an expansion perspective view which looked at from above. This putter has a shaft 10 made of metal, carbon, or the like that tapers from the root to the tip. On the front surface of the outer periphery of the shaft 10, for example, a guideline 11 having a predetermined size is formed in parallel with the central axis of the shaft 10. A head 20 made of metal or the like is fixed to one tapered end of the shaft 10, and a grip 30 made of rubber or leather is attached to the other end of the base of the shaft 10. The head 20 includes a face surface 21 for hitting a ball, a top portion 22 extending above the face surface 21, a goose type neck portion 23 protruding upward from the top portion 22, It is composed of a back portion 24 extending behind the top portion 22 and a sole portion 25 extending below the face surface 21 and the back portion 24, and has a weight Ma of about 340 g. A cavity 27 is formed between the toe side 26 a and the heel side 26 b of the back portion 24 of the head 20. The cavity 27 has a function of distributing the weight between the toe side 26a and the heel side 26b to improve the moment of inertia and prevent the head 20 from shaking at the time of impact. A groove-shaped guide line 28 is formed in the top portion 22 on the sweet spot of the head 20 and in a direction perpendicular to the face surface 21. The guideline 28 has a guide function for aligning the face surface 21 with the squae with respect to the flight line and for aligning the sweet spot of the head 20 with the center of the ball. A shaft insertion hole 23a is formed at the upper end of the goose type neck portion 23, and one end of the shaft 10 is inserted and fixed in the shaft insertion hole 23a. The outer circumference H of the sole portion 25 is smaller than the conventional one, for example, 23.3 cm, and the area Sa of the outer circumference H is 22.5 cm ² .

The grip 30 attached to the other end of the shaft 10 has a diameter considerably larger than that of the conventional one, and its weight Mb is, for example, about 140 g. A marker insertion hole 32 is formed in the end portion 31 of the grip 30. On the end portion 31, for example, a guide mark 33 is formed in parallel with the guide line 28 of the top portion 22. The guide mark 33 has a function of correcting the directionality of the face surface 21. The grip length L is, for example, 27.3 cm. The grip length near the end portion 31 is L1, the grip length from the end portion 31 to the grip tip portion is L4, and the grip length from the end portion 31 when the grip 30 is divided into three is L2 and L3. If the outer circumferences of the grip lengths L1, L2, L3, L4 are G1, G2, G3, G4, and the area of the outer circumference G1 is Sb, the respective dimensions and the like are set as follows. Grip length L1 = 1.3 cm, L2 = 9.2 cm, L3 = 17.5 cm, L4 = 26. 3 cm, their outer circumference G1 = 12.0 cm, G2 = 10.0 cm, G3 = 9.0 cm, G4 = 6.7 cm, and the area Sb of the outer circumference G1 is 7.5 cm ² . The weight Ma of the head 20 and the weight Mb of the grip 30 are set within the range of 3: 1 to 1: 1 and the area Sa of the sole portion 25 and the area Sb near the grip end portion are 3: 1 to 1: 1. However, in the present embodiment, they are Ma: Mb = 340 g: 140 g (= 3: 1) and Sa: Sb = 22.5 cm ² : 7.5 cm ² (= 3). : 1) is set.

Next, an example of a putting method using the putter configured as described above will be described. For example, when putting a ball on a cup on the green, grasp the grip 30 of the putter, address and read the flight line in the cup direction. Then, the guide line 28 of the top portion 22 is set in the direction of the flying ball line, and the face surface 21 is squared with respect to the flying line. At this time, since the distance from the eye position to the guideline 28 of the top portion 22 is long, it is difficult to correctly set the guideline 28 in the flight line direction. Therefore, if the direction of the face surface 21 is adjusted with reference to the guide line 11 on the shaft 10 and the guide mark 33 of the end portion 31 of the grip 30, the face surface 21 will not be opened or closed. In addition, the face surface 21 can be set in a square easily and accurately. Next, when the head 20 is stroked in the flight line direction with reference to the guide line 28 of the top portion 22, the ball is hit by the sweet spot of the head 20 and rolls in the cup direction.

This embodiment has the following advantages (i) and (ii). (I) In conventional putters, the head weight is usually around 330g, the grip weight is around 70g, the weight ratio of the head to the grip is 330g: 70g = 5: 1, the bottom area of the sole part is around 24cm ² , and the grip end is around. Has a cross-sectional area of about 6 cm ² and the area ratio between the sole and the grip end is 24 cm ² : 6 cm ² = 4: 1. On the other hand, in this embodiment, for example, the head weight Ma is around 340 g, the grip weight Mb is around 140 g, the weight ratio between the head 20 and the grip 30 is Ma: Mb = 340 g: 1 40 g = 3: 1, and the sole area is Sa is around 22.5 cm ² , the area Sb near the grip end is 7.5 cm ² , and the area ratio is Sa: Sb = 22.5 cm ² : 7.5 cm ² = 3: 1. Therefore, the grip 30 of the present embodiment has a heavier weight than that of the conventional grip 30, and thus the stroke is significantly facilitated. In addition, the weight ratio of the head 20 to the grip 30 is 3: 1 and the weight of the grip 30 is heavier than that of the head 20, so that the directionality and distance feeling during putting can be easily obtained. be able to. Further, the area ratio between the sole portion 25 and the grip end is Sa: Sb = 3: 1. Due to the combination of the area ratio and the weight ratio, excellent directionality which cannot be achieved by the conventional putter is obtained. A sense of distance can be realized. (Ii) In this embodiment, the guide line 11 is formed on the shaft 10 and the guide mark 33 is formed on the end portion 31. Since the guide line 11 and the guide mark 33 are close to the eyes, it is easier to align the face surface 21 with the flying ball line in a square shape.

The present invention is not limited to the illustrated embodiment, and various modifications can be made. Examples of such modifications include the following. (1) In the above embodiment, the weight ratio between the head 20 and the grip 30 is set to Ma: Mb = 3: 1, and the area ratio near the sole portion 25 to the grip end is set to Sa: Sb = 3: 1. If these are within the ranges of Ma: Mb = 3: 1 to 1: 1 and Sa: Sb = 3: 1 to 1: 1, the same effects as those of the above-described embodiment can be obtained. (2) A cavity 27 is formed in the head 20, and the moment of inertia is improved by weight distribution between the toe side 26a and the heel side 26b. However, even for a head structure without such a cavity 27, By setting within the ranges of Ma: Mb = 3: 1 to 1: 1 and Sa: Sb = 3: 1 to 1: 1, a putter excellent in directionality and sense of distance can be obtained. In this case, the guide lines 11 and 28 and the guide mark 33 may not be provided. (3) The guide line 28 formed on the top portion 22 is composed of one groove-shaped line, but it is possible to form them with a plurality of groove-shaped lines, to manufacture them, to manufacture them, or to Mark, or may be formed at another position such as the cavity 27 side. (4) The guide mark 33 formed on the end portion 31 may be changed into various shapes and patterns such as a cross shape or a symbol such as a manufacturer name which is long and thin in the lateral direction. (5) The guideline 11 formed on the front surface of the outer periphery of the shaft 10 may be changed to a shape elongated in the longitudinal direction by using a manufacturing name or the like.
